Title

An Extension Study to Evaluate Safety and Efficacy of BMN 111 in Children With Achondroplasia

Study Description

This Phase 2, open-label, multicenter, long-term extension study, with approximately 70 subjects, evaluates the safety and efficacy of BMN 111 (vosoritide) in children with achondroplasia until subjects reach near-adult final height.

Primary Outcome Measures*

  • Evaluate the incidence of treatment-emergent adverse events
  • Evaluate change in height/length z-score in children with ACH treated with vosoritide

Select Inclusion Criteria*

  • Must have completed Study 111-206 on investigational treatment
  • Parent/guardian provides informed written consent if required

Secondary Outcome Measures*

  • Evaluate the change from baseline in mean annualized growth velocity
  • Characterize maximum concentration

Select Exclusion Criteria*

  • Permanently discontinued vosoritide or placebo prior to completion of Study 111-206
  • Have a clinically significant finding or arrhythmia on ECG that indicates abnormal cardiac function or conduction or QTc-F >450 msec

* Additional measures/criteria may apply.
ACH, achondroplasia; ECG, electrocardiogram; QTcF, corrected QT interval by Fridericia.

Study Description

This is a Phase 2 randomized, open-label clinical trial of BMN 111 (vosoritide) in infants and young children with a diagnosis of achondroplasia at a heightened risk of requiring cervicomedullary decompression surgery.

Primary Outcome Measure*

  • Incidence of treatment-emergent adverse events

Select Inclusion Criteria*

  • Parent/guardian provides informed written consent if required
  • Have ACH, documented by genetic testing

Secondary Outcome Measure*

  • Evaluate the effect of vosoritide on total foramen magnum volume

Select Exclusion Criteria*

  • Have hypochondroplasia or short-stature condition other than achondroplasia
  • Have CMC that either does not require surgical intervention or does require immediate surgical intervention

* Additional measures/criteria may apply.
ACH, achondroplasia; CMC, cervicomedullary compression.

  • Characterize maximum concentration of vosoritide in plasma

Select Exclusion Criteria*

  • Permanently discontinued vosoritide or placebo prior to completion of Study 111-301
  • Have a clinically significant finding that indicates abnormal cardiac function
  • Evidence of slowed growth of at least 6 months or closed growth plates in lower extremity X-rays

* Additional measures/criteria may apply.
